81-427: A joint project between Paraguay and Argentina. The massive reservoir formed by the project has been the source of a number of problems for people living along the river, most notably the poorer merchants and residents in the low-lying areas of Encarnación, a major city on the southern border of Paraguay. River levels rose dramatically upon completion of the dam, flooding out large sections of the city's lower areas. From

108-619: A series of seven cascades. This natural feature was said to rival the world-famous Iguazu Falls to the south. The falls were flooded, however, by the construction of the Itaipu Dam , which began operating in 1984. For approximately the next 200 km (120 mi), the Paraná flows southward and forms a natural boundary between Paraguay and Brazil until the confluence with the Iguazu River . Further upstream from this confluence, however,

189-740: Is up to 100 metres (330 ft) below the bottom of the river channel and it is 1/8 to 1/3 as wide as the river. The canyon is only visible in two places, one of which is the Moconá Falls (also called the Yucumã Falls). However, the falls are not visible for 150 days per year and become more like rapids when they are not visible. Unlike most waterfalls , the Moconá Falls are parallel to the river, not perpendicular . The falls are 10 metres (33 ft) to 12 metres (39 ft) high and between 1,800 metres (5,900 ft) and 3,000 metres (9,800 ft) wide. They are 1,215 km (755 mi) from

243-591: The Pelotas River are joined, at about 200 metres (660 ft) above mean sea level . At this stage, the river goes through uneven, broken terrain, forming rapids and falls. Its course through Rio Grande do Sul is not navigable. An unusual feature of the Uruguay River is a submerged canyon . This canyon formed during the Ice Age , when the climate was drier and the river was narrower. Its depth

The Parana River delta ranks as one of the world's greatest bird-watching destinations. Much of the length of the Paraná is navigable , and the river serves as an important waterway linking inland cities in Argentina and Paraguay with the ocean, providing deepwater ports in some of these cities. The construction of enormous hydroelectric dams along

297-542: The Paraná River was the Venetian explorer Sebastian Cabot , in 1526, while working for Spain. A drought hit the river in 2021, causing a 77-year low. In eastern South America there is "an immense number of river names containing the element para- or parana- ", from Guarani language words meaning "river" or "sea"; attempts to derive a more precise meaning for the name of this, the largest of them, e.g. "kin of

If the Uruguay River is counted as a tributary to the Paraná, this watershed extends to cover most of Uruguay as well. The volume of water flowing into the Atlantic Ocean through

351-515: The Río de la Plata roughly equals the volume at the Mississippi River delta . This watershed contains a number of large cities, including São Paulo , Buenos Aires , Rosario , Asunción , Brasília , and La Plata . The Paraná and its tributaries provide a source of income and of daily sustenance for fishermen who live along its banks. Some of the species of fish (such as the surubí and

378-582: The Uruguay River has an area of 365,000 km (141,000 sq mi). Its main economic use is the generation of hydroelectricity and it is dammed in its lower portion by the Salto Grande Dam and by the Itá Dam upstream in Brazil.

The drainage basin of

432-506: The Uruguay River. Argentina alleged that Uruguay broke the treaty. Additionally, Argentina believed the Finnish company Botnia was polluting the fish and the overall environment of the river while Uruguay believed that the plant was not depositing a large amount of toxins in the Uruguay River.

This flows into the Atlantic Ocean . During the part of its course downstream from

513-477: The dispute before the International Court of Justice . The ICJ completed hearings between Argentina and Uruguay regarding the dispute on October 2, 2009. In 2010, the court ruled that although Uruguay failed to inform Argentina of the construction of the pulp mills, the mills did not pollute the river, so closing the remaining pulp mill would be unjustified. Later in 2010, Argentina and Uruguay created

540-584: The mouth of the river. The 17,491 ha (43,220 acres) Turvo State Park , created in 1947, protects the Brazilian side of the falls. Together with the Paraná River , the Uruguay forms the Río de la Plata estuary . It is navigable from around Salto Chico . Its main tributary is the Río Negro , which is born in the south of Brazil and goes through Uruguay for 500 km until its confluence with

567-473: The mouth: tributary tributary (km) (km ) (m /s) Yabotí Guazú Antes Period: 1971–2000 Argentina and Uruguay experienced a conflict over the construction of pulp mills on the Uruguay River. Two European companies, ENCE and Botnia, proposed building cellulose processing plants at Fray Bentos , Uruguay, opposite Gualeguaychú , Argentina.

After merging with the Iguazu, the Paraná becomes the natural border between Paraguay and Argentina. Overlooking the Paraná River from Encarnación, Paraguay , across

675-493: The river's length has blocked its use as a shipping corridor to cities further upstream, but the economic impact of those dams offsets this. The Yacyretá Dam and the Itaipu Dam on the Paraguay border have made the small, largely undeveloped nation of Paraguay the world's largest exporter of hydroelectric power . Due to its use for oceangoing ships, measurements of the water tables extend back to 1904. The data correlates with

From the confluence the river flows in a generally southwestern direction for about 619 km (385 mi) before encountering the city of Saltos del Guaira , Paraguay. This was once the location of the Guaíra Falls (Sete Quedas waterfalls, where the Paraná fell over
